If a fixed term standard contract contains a contract-holder's break clause, it may provide that if there are joint contract-holders, a notice given to the landlord by one or more (but not all) of them that purports to be a notice under the break clause is to be treated as a notice that the joint contract-holder intends (or the joint contract-holders intend) to withdraw from the contract ("a withdrawal notice").
If it does so, it must also make provision equivalent to subsections (4) and (5) of sections 111 and 130.
